Q2. Where you initialise driver
Ans. 
The driver is typically initialized in the setup method of a test automation framework.
• Driver initialization is usually done in a setup method before test execution.

• Commonly used methods for driver initialization include WebDriverManager, System.setProperty, and driver instantiation.

• Example: WebDriverManager.chromedriver().setup();

Q3. Driver is static or non static
Ans. 
Driver can be both static and non-static depending on the context of its usage.
• Driver class can be static if it is used to initiate the WebDriver instance in a test automation framework.

• Driver class can be non-static if it is used as an instance variable within a test class.

• Static driver can be accessed directly without creating an object of the class.

• Non-static driver requires an object of the class to be created befo

Q4. Difference between static and non static
Ans. 
Static variables belong to the class itself, while non-static variables belong to instances of the class.
• Static variables are shared among all instances of a class

• Non-static variables are unique to each instance of a class

• Static variables are initialized only once, at the start of the program

• Non-static variables are initialized separately for each instance of the class

Q5. Disadvantages of static and non static
Ans. 
Static and non-static have their own disadvantages in QA automation testing.
• Static methods cannot be overridden or inherited, making it difficult to create flexible test cases.

• Non-static methods require an instance of the class to be created, which can lead to increased memory usage.

• Static methods can lead to tight coupling between classes, making it harder to maintain and update the code.

• Non-static methods may have de...read more

Q6. Parallel execution in TestNG
Ans. 
TestNG allows parallel execution of test cases to save time and improve efficiency.
• TestNG provides the 'parallel' attribute in the testng.xml file to specify the level of parallelism for test execution.

• Parallel execution can be achieved at the test level, class level, method level, or suite level.

• TestNG also supports parallel execution of tests across multiple classes or suites using the 'parallel' attribute in the sui...read more

Q7. Write the code for Parallel testing in TestNG
Ans. 
Parallel testing in TestNG allows running tests concurrently for faster execution.
• Use 'parallel' attribute in testng.xml file to specify parallel execution mode.

• Set 'parallel' attribute to 'methods', 'classes', or 'tests' based on the level of parallelism needed.

• Example: <suite name='MySuite' parallel='tests'>

• Use 'thread-count' attribute to specify the number of threads to use for parallel execution.

Q14. How cucumber know step defination file placed
Ans. 
Cucumber knows the step definition file based on the annotations provided in the feature files.
• Cucumber uses annotations like @Given, @When, @Then to map steps in feature files to corresponding step definition methods.

• Step definition files are typically placed in a separate package or directory within the project structure.

• Cucumber scans the project directory for step definition files based on the package structure and

Q16. Datatable in cucumber
Ans. 
Datatable in Cucumber is used to pass multiple sets of data to a step definition in a scenario.
• Datatables are defined using pipes (|) to separate values

• Each row in the datatable represents a set of data passed to the step definition

• Datatables can be used for parameterization and data-driven testing

Ans. 
The output of the code will be 'animal is created' followed by 'Dog is created'.
• The code defines a class Animal with a constructor that prints 'animal is created'.

• It also defines a class Dog that extends Animal, with a constructor that prints 'Dog is created'.

• In the main method, an instance of Dog is created, which will trigger the constructors of both Animal and Dog classes.
